Really? Yet Another Web Framework/CMS?

YetaWF (pronounced "Yet Another Web Framework") is a new open source product, developed by Mike van der Meulen (Softel vdm, Inc.). It was used to develop and host the company's own site, the LinksWithPics service, the WEO Report service (now discontinued), this site and various other sites.

It builds on ASP.NET Core MVC to create a web framework/CMS for developers. While it has many attributes commonly found in today's CMS like DotNetNuke, Umbraco, Drupal, etc., it instead focuses on rapid application development. Tightly integrating with Visual Studio 2015/2017, it lends itself to rapid module development, offering built-in BREAD (Browse, Read, Edit, Add, Delete) module generation, taking advantage of ASP.NET, Data Annotation, Templated Helpers, UIHint and many other innovative features made possible by ASP.NET. Rather than being all things to all people, it narrowly focuses on offering 100% of the features that will satisfy most average websites and offers a platform for rapid custom development.

It has been in development since 2010, upgraded from MVC 3 to 4, 5 and now supports ASP.NET Core MVC. It has been used since then to host numerous sites. It's definitely not a beta version, but may need some extra documentation, which is in the works. With the move to ASP.NET Core all of YetaWF's features are available and other than a lot of framework code that had to be changed, all modules were ported with minimal source code changes, resulting in an immediately mature product.

YetaWF makes extensive use of jQuery, jQuery-UI, Ajax and many client-side plugins (like grids, menus, syntax highlighter, lightbox, CKEditor, tabs, overlays and many more). It combines these with automatic features like JavaScript and CSS minifier and bundling, http response compression (take a look at the source for this page) without burdening the developer with administrative tasks. No build pipeline to set up or maintain.

YetaWF offers easy to design Single Page Sites, Static Pages and of course traditional multi-page sites, all easily created with modules that are added to pages. YetaWF also takes a new approach to localization by being designed from the ground up with localization in mind (again, without burdening the developer with administrative tasks). Pages, modules, down to SQL tables or file data are fully localizable. Adding/removing languages is possible at any time, not just at design-time. Even upgrading is super simple. We have a special upgrade utility that will upgrade your site, even if you skipped a few versions.

For the site administrator, it offers site management, automated backups, easy version upgrades, scheduled tasks and of course complete control over authentication and user/role authorizations. And you can even use it on your phone/tablet without downloading any apps, with full access to all administrator features.

Try our Demo Site which lets you log into YetaWF as a Superuser so you can see all the Administrator features (you can't make any changes to the site).

Latest News

YetaWF 2.7.0 Released on November 25, 2017

  • The location of all JavaScript files (<script src= > tags) can now be defined through Site Settings, either at the top or at the bottom of pages. This way we don't have to take sides in the debate which location is better. Placing them at the top of pages minimizes the "Flash of Unformatted Content" effect.
  • The location of all Css files (<link href= > tags) can now be defined through Site Settings, either at the top or at the bottom of pages. This way we don't have to take sides in the debate which location is better. Placing them at the top of pages minimizes the "Flash of Unformatted Content" effect.
  • When JavaScript or Css files are placed at the bottom of pages, JavaScipt/Css is injected that minimizes the "Flash of Unformatted Content". This feature is automatic and can be disabled in Site Settings.
  • A separate cookie-less domain can be defined to serve just static files  (css, js, png, etc.) to improve site performance. See Admin > Site Settings > CDN tab.
  • New TawkTo package implementing live chat with a account (basic accounts are free).
  • Simplified CDN setup (only static files are served using a CDN).
  • JavaScript/Css bundles for Unified Page Sets (SPA) are discontinued. All previously bundled JavaScript/Css is now returned as part of the response to the initial Ajax request. (This is so much better).
  • Simplified Bootstrap Carousel editing.
  • New grid action dropdown menu (instead of icons). User selectable in User > Settings. New sites default to dropdown menus.
  • Support for new (replaced) Microsoft Translator Text API.
  • New Panels package: Panel module with support for navigation between multiple modules added to the Panel module using tabs or accordion.
